As a state visit looms … can the king tame Trump?

Royal visitors have long been popular in the US, and Charles has decades of diplomacy under his belt. But can soft power save the special relationship?

What's the worst that could happen when King Charles visits Donald Trump in Washington at the end of this month? And what will be the best outcome from Keir Starmer's point of view, since it is the prime minister who directed the visit to go ahead in the hope of improving our battered, supposedly special relationship? While the relationship is still apparently meaningful to Britain, to the US it appears to not mean so much - especially now.

The king goes where he is told, whether he would prefer to stay at home or not. This time to a land whose president denounces our aircraft carriers as toys and accuses us of cowardice, and whose defence secretary talks derisively of our Royal Navy. Perhaps Charles ought to wear his naval admiral's uniform when he goes to the White House, medals and all.
